The ninth son of the First Emperor of Qin, Ying Mu, was swinging a hammer to forge something in the backyard of the Prime Minister's Mansion. When the iron billet was about to be completed, Li You urgently reported that his father had arrived outside the courtyard! The hammer deflected and cracked the iron embryo, leaving deep marks. I frowned: ruined... Ying Zheng was approaching Zhangtai Palace, and his angry shouts were still in my ears. This fire can't extinguish this iron tool, so I have to cast it for him!
